Use of inorganic particles to produce a barrier layer on aircraft components

Abstract

A plastics material component for an aircraft includes (i) a substrate, which comprises one or more thermosetting plastics materials, and (ii) one or more layers which are applied to the substrate, at least one layer S1 comprising mica. A method for producing the plastics material component includes providing a substrate including at least one thermosetting plastics material or one polymer which is crosslinked to form a thermosetting plastics material, and applying one or more layers to the substrate, wherein at least one layer includes mica. The mica-containing layer is applied directly to the substrate and the application is carried out before and/or during the curing of the thermosetting plastics material.

The invention claimed is: 
     
       1. A method for producing a plastics material component for an aircraft comprising (i) a substrate, comprising one or more thermosetting plastics materials, and (ii) one or more layers applied to the substrate, at least one layer comprising mica, the method comprising:
 providing a substrate, comprising at least one thermosetting plastics material or one polymer which is crosslinked to form a thermosetting plastics material, and 
 applying one or more layers to the substrate, at least one layer comprising mica; 
 wherein the mica-containing layer is applied directly to the substrate and the application is carried out before and/or during the curing of the thermosetting plastics material, and 
 wherein the mica-containing layer is applied to the substrate by an electrostatic application method, and 
 wherein a mica layer is applied to a foil and held on the foil surface by electrostatic interactions, and the mica layer provided on the foil is subsequently transferred to the substrate to form the mica-containing layer. 
 
     
     
       2. The method according to  claim 1 , wherein the substrate is in the form of a prepreg. 
     
     
       3. The method according to  claim 1 , wherein the substrate is provided in the form of a prepreg which already comprises a mica-containing layer.
